4. INTRODUCTORY PROPAGATION (40 hours duration)
The purpose of this study area is to improve the student's understanding of propagation techniques with particular emphasis on cuttings and seeds. Other industry techniques such as grafting and budding are also explained.
Aims
- Demonstrate propagation of six (6) different plants by cuttings and three from seed.
- Construct a simple inexpensive cold frame.
- Mix and use a propagation media suited to propagating both seed and cuttings.
- Describe the method and time of year used to propagate different plant varieties.
- Describe and demonstrate the steps in preparing and executing a variety of grafts and one budding technique.
- Explain the reasons why budding or grafting are sometimes preferred propagation methods.
5. IDENTIFICATION AND USE OF PLANTS (60 hours)
The purpose of this study area is to improve the student's range of plant knowledge and the plant use in landscaping and the ornamental garden, and the realization that plants have optimum and preferred growing conditions.
Aims
- Select plants appropriate for growing in different climates.
- Select plants appropriate to use for shade, windbreaks, as a feature, and for various aesthetic effects.
- Categorise priorities which effect selection of plants for an ornamental garden.
- Explain the differences in the way plants perform in different microclimates within the same area.
- List and analyze the situations where plants are used.
6. PESTS, DISEASES AND WEEDS (50 hours)
The purpose of this study area is to introduce and help the student in identifying, describing and controlling a variety of pests, diseases and weeds in ornamental situations and safety procedures when using agricultural chemicals are explained.
